"I can't think of a good reason to call pthread_self a lot.
why?"
It's a long story, but basically I need a way of accessing application specific "context" information I have stored which is different depending on which thread is running. Using pthread_self() provides a way of having a unique key to that information regardless of where within a program, the execution is. Because pthread_self doesn't require any arguments, I don't need to carry around a parameter everywhere with that key, hence the application doesn't even have to be aware of the mechanism.
Hopefully that makes sort-of sense.
